These high quality, below ground submersible pumps are designed for residential and small municipal water supply as well as light irrigation applications. They are constructed with a cast 303 stainless steel discharge head and motor adapter, superior sand handling capability, built-in stainless steel check valve, and a Centripro motor designed for continuous operation.

Note: This is a 3 wire pump that requires a control box for operation, but is not included. Choose this if you are replacing the same exact motor/pump and already have a control box for a Centripro motor with the same horsepower rating.

Features and Accessories

Product Features

Powered for Continuous Operation: All ratings are within the working limits of the motor as recommended by the motor manufacturer. Pump can be operated continuously without damage to the motor.Field Serviceable: Units have left hand threads and are field serviceable with common tools and readily available repair parts.Sand Handling Design: Our face clearance, floating impeller stack has proven itself for over 40 years as a superior sand handling, durable pump design.FDA Compliant Non-Metallic Parts: Impellers, diffusers and bearing spiders are constructed of glass filled engineered composites. They are corrosion resistant and non-toxic.Discharge Head/Check Valve: Cast 303 stainless steel for strength and durability. Two cast-in safety line loops for installer convenience. The built-in check valve is constructed of stainless steel and FDA compliant BUNA rubber for abrasion resistance and quiet operation.Motor Adapter: Cast 303 stainless steel for rigid, accurate alignment of pump and motor. Easy access to motor mounting nuts using standard open end wrench.Stainless Steel Casing: Polished stainless steel is strong and corrosion resistant.Hex Shaft Design: Six sided shafts for positive impeller drive.Engineered Polymer Bearings: The proprietary, engineered polymer bearing material is strong and resistant to abrasion and wear. The enclosed upper bearing is mounted in a durable Noryl® bearing spider for excellent abrasion resistance.

Important: Any well with a high static water level may allow the pump to operate off the curve and outside its recommended range. We recommend using a "Dole" flow restriction valve to throttle the pump to prevent upthrust damage to the pump and motor. The maximum flow must be restricted to within the pumps recommended operating range.

A calibration adjustment allows the Model 235P to be calibrated to your specific pumping applications, thereby reducing the possibility of false or nuisance tripping. A unique microcontroller-based voltage and currentsensing circuit constantly monitors the incoming power for fluctuations causing overcurrent and undercurrent. When an abnormality, such as loss of suction is detected, the PumpSaver® Plus deactivates its output relay and directly disconnects the pump motor. The PumpSaver® Plus then begins its user-selectable “Restart Delay” (dry-well recovery) timer. When the timer expires or power is removed and reapplied, the PumpSaver® Plus reactivates its output relay and allows the pump to turn back on.

The Model 235P communicates with a hand-held diagnostics tool called the Informer (sold separately). The Informer displays 15 parameters including calibration points, trip points, running points, and last faults.

The torque arrestor is used to prevent motor start up torque from thrusting the pump against the side of the well casing. Think of it as a shock absorber for your well system.

Placement: The first torque arrestor should be placed 1' or 2' above the pump. Then at intervals of 75' to 100' above the first torque arrestor.Installation: Place the torque arrestor around the drop pipe so that each half is spaced evenly.

Install the lower pipe clamp and tighten.

Install the upper pipe clamp (leave loose) and then push down on the torque arrestor to spread the center portion so it fits the inside of the casing.

Just a snug fit, do not spread it so much that it is hard to get it in the casing. Then tighten the upper clamp. It is very important that the upper clamp is as tight as possible. This will make it easier to remove the pump at a later date.

PurposeThe lightning arrestor is designed to protect motors and controls from voltage surges caused by lightning, switching loads, or power line interferences. Surges of 500 volts or more are directed to ground by the lightning arrestor. Although the arrestor may or may not take repeated surges, no arrestor can withstand a direct lightning strike or a surge of unusually high voltage.

ApplicationThe Heavy-Duty Models lightning arrestor have Threads and Nut to Attach to Electrical Panel or varieties of enclosed motor controls.Including:WELL PUMP CONTROLS (2 WIRE OR 3 WIRE MOTORS)1. Pressure Switch2. Control Box3. Both the pressure switch and control boxNote: Pressure switch arrestor location offers the best water system protection, if only one lightning arrestor is used.

WARNING: It is very important that all electrical work be done properly. Therefore, only a qualified electrician or electrical service man should perform the initial hook-up and any electrical service thereafter! All local electrical codes must be followed.
